Omsk refinery hit trims Polymarket odds for United Russia lead to 54.5%

Omsk Refinery Drone Strike Hits Russia’s Fuel Outlook, Nudging United Russia’s Polymarket Odds Down to 54.5%

A reported Ukrainian drone strike that halted operations at Russia’s largest oil refinery in Omsk added fresh pressure to Russia’s domestic fuel outlook, a backdrop that can influence perceptions of political stability ahead of the next parliamentary vote. On Polymarket, traders slightly trimmed the market’s implied probability that United Russia (ER) will gain the most seats in the Russian parliamentary election.

Key Takeaways

• Polymarket prices United Russia (ER) as the leading outcome at 54.5% to gain the most seats.
• The contract’s leader slipped by 1.0 percentage point from 55.5% as news of a major refinery halt raised attention on domestic strains.
• The market is set to resolve on 2026-09-20, with total volume at $14,651,817.

Russia’s largest oil refinery in Omsk, owned by Gazprom Neft, reportedly halted operations after a Ukrainian drone strike on Monday, according to two industry sources cited in a Reuters report. The refinery is about 3,000 km (1,864 miles) from Ukraine and processed 22 million metric tons of crude in 2024, producing about 5 million tons of gasoline and 8 million tons of diesel. A Russian presidential envoy confirmed the facility sustained damage and said specialists were assessing it and conducting restoration work, while stating no personnel were injured. The sources said the CDU-10 crude distillation unit, which accounts for roughly 38% of capacity, was damaged and caught fire, and that a second primary unit, CDU-11, representing about 37% of capacity, was also shut due to damage to supporting infrastructure. Exchange data cited in the report indicated the refinery suspended gasoline and diesel sales on the St. Petersburg International Mercantile Exchange starting Tuesday.

Russian Election Market Sees $14.65M Volume as United Russia Slips 1 Point (55.5% → 54.5%) While New People Holds 40.25%

Polymarket’s multi-outcome market, “Which party will gain most seats in Russian Parliamentary Election?”, shows United Russia (ER) leading at 54.5% Yes versus 45.5% No on $14,651,817 in volume. New People (NL) is the main alternative at 40.25% Yes and 59.75% No, while the rest of the field is priced as long shots, including LDPR at 3.55% Yes/96.45% No and KPRF at 1.85% Yes/98.15% No. The latest move reflects a narrow drift lower in the leader’s pricing, with the contract still concentrated in a two-way race between ER and NL by implied odds. The market remains active ahead of its 2026-09-20 resolution date.

Whether refinery operations restart quickly and whether fuel sales and supply conditions normalize, which could shape the risk backdrop traders may try to express through positioning in the election market.
